Abstract

In order to discuss the failure mechanism of concrete filled steel tube lattice wind turbine tower joints. Based on the parameters of abdomen strut section form, and using nonlinear static numerical simulation, this article research on the stressed complex joints. The results of the study show that the abdominal rod for circular steel tubes node (JD1) is the local buckling of compressive bar that causes instability and failure; The abdominal rod for single angle steel (JD2) or double angle steel (JD3) node is local buckling instability that cause the failure of node board. Under the abdomen stem and node board all meeting their own capacity requirements, JD1 is very easy to make draw bar broken on both sides of the pillar tube wall region, JD2 and JD3 are apt to damage on the weak positions of node board ends and pillar tube wall joint. In the three web members node form, the highest ultimate bearing capacity is JD1 and JD3 is the second and JD2 is minimum.
